How Multispectral and Hyperspectral Imaging are Improving Recycling

Author: Geralyn MillerMonday, September 25, 2017A new generation of multispectral and hyperspectral cameras is increasing the purity of many recycled materials to close to 100%. These cameras divide light into hundreds of narrow bands over a continuous range that spans the electromagnetic spectrum. The cameras collect hundreds of data points per pixel and combine these to generate a unique spectral signature (also called a fingerprint) for each material based on its chemical composition.
Read how these systems are being used to improve the sorting of two of the most common and difficult-to-sort waste materials—plastics and papers.
